5. Bayanin Injiniya & Kunshin

The LED is housed in a 3.1mm diameter round package with a water-clear lens. Key dimensional notes include: all dimensions are in millimeters (with inch equivalents), with a standard tolerance of ±0.25mm unless specified otherwise. The resin under the flange may protrude up to 1.0mm maximum. Lead spacing is measured at the point where the leads emerge from the package body. A detailed dimensioned drawing would typically show the body diameter, lens shape, lead length, and lead diameter, which are critical for PCB footprint design and panel cut-out sizing.
